To (0Z5 whom it may concern.-

Be it known that 1,-HARRY M; MCCALL, a citizen of the United States, residing at Pittsburg, in the county of AlleghenyandiState of Pennsylvania, have inventedcertaiirnew and useful Improvements in Air superheaters or Carbureters, of which the following is a specification, reference being had to the accompanying drawings. f I

This invention has relation to a'ir. superheaters or carbureters; and it consists in the novel construction and arrangement'of its parts, as hereinafter described.

The object of this invention is to provide a device for use either for superheatingair or for carbureting elements andfor converting hydrocarbon into gas.

It consists, primarily, of a heating chamher into which the elements areintroduced under pressure, the said heating-chamber being provided in its interior with a means for spraying or forcing elements as they are introduced against the heated sides of the said chamber, the elements in gaseous state passing from the heating-chamber into. the

upper end of a coil. Said coil surrounds a reservoir, to one end of which one endof the coil is attached. h state may be delivered from the reservoir to any desired point.

In the accompanying drawings, Figure 1 is p M Fig. 2 is a horizontal sectional view out on the line 2 2.

support 3, passing through the si'de'of the said chamber. The needle-valve; casing4 enters one end ofthe chamber 1,-the inner end of said casing being provided with'a valve-seat 5, the hollow needle-valve 6 passing longitudinally through said casing. The rear end The element in gaseous of the saidineedle-valve 6 is threaded, as at 7, and engages an interior thread of the tap 8, whereby by turning the said needle-valve 6 it maybe passedin orout of the seat 5, thus opening or closing the space between the point end of. said needle-valve and the said seat andincrease or diminish accordingly the capacity of the-passage of the elements at this point. The lateral openings 9 communicate thelinterior of the needle-valve 6 with the exterior justat the point where said ne'edle-valve begins'to taper. The tap 8 closes the rear end of the valve-casing 4, and the inletpipalO-is connected with the side of said casing. The pipe 11 is connected with the opposite end of the heating-chamber 1, said pipe .11 being connected with the coil 12, said coil surrounding the hollow reservoir 13, the otherend of said coil 12 entering said reservoir 13at the point 14 at the bottom of the samegthe said reservoir'l3 being provided at its topwith a suitable outlet 15.

In; operation the device works as follows:

.Theffiame of the heatingmeans 16is brought 'in contact with the heating-chamber 1, as

shown-in Fig. 3. The walls of said chamber are thus increased in temperature. Presuming that the device is to be used for heating air, the saidelement under pressureis introducedthrough the inlet-pipe 10 into the valvecasing 4, the outer end of the needle-valve 6 having previously been closed, the said needlefvalve being so set with relation to the valve-seat 5 as to permit the requisite quantity of air to pass through: the said seat 5.

' As the air passes into the chamber 1 it strikes the side of the sphere 2 and is deflected in all directions against the hot sides of the said chamberl. Thus the air is heated. It then passes through the pipe 11 into the coil 12, said coil taking up the heat passing above the chamber 1. The said air while in the coil is superheated and eventually enters the res ervoir 13 in this condition, from which place it maybe conducted to any desired point.

To use the apparatus as a carbureter the airis introduced in a manner asabove described. At the same time hydrocarbon is ICC air as it passes through the valve-seat 5. The mixture of hydrocarbon and air is forced against the sphere 2 and is instantly converted into a gas, which is subjected to the same action as that above described for the air.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A device of the character as described, consisting of a heating-chamber, a sphere located in said chamber and adapted to deflect the elements as they are introduced into the chamber against the walls of the same.

2. An apparatus of the character as described, consisting of a heating-chamber, a deflecting means located within said chamber,

a valve-casing connecting said chamber, said casing having an inlet, a hollow needle-valve located in said casing and a means for adjusting said valve. i

3. A device of the character as described, consisting of a heating-chamber, a deflector located in the interior of said chamber, a valve-casing connecting said chamber, said Valve-casing having an inlet, a hollow needlevalve located within the casing and a means for adjusting said needle-valve with relation to the casing to regulate the capacity of the opening into the chamber.

4. A device of the character as described,

consisting of a heating-chamber, a deflector located in said chamber, a means for introducing an element into the chamber against said deflector, a coil connected with said chamber andlocated above the heating means, a reservoir being connected with said coil and also being located above said heating means.

5. A device of the character as described, consisting of a heating-chamber, a deflector located in said chamber, a valve-casing en-
